Abstract

Recent reports of the criteria pollutants in the Megalopolis, located in the central part of Mexico, consistently show air quality standard exceedances in most of the cities that make it up, since it is a large concentration where approximately 17% of the national population resides and because it has significant commercial and industrial development. To investigate the similarities and disparities in risk perception concerning air pollution and climate change among residents living in Central Mexico, a cross-sectional survey study was carried out within three metropolitan areas encompassed by the Megalopolis. A total of 1750 questionnaire surveys were conducted across 21 municipalities within the Mexico City Metropolitan Area (MCMA), 16 municipalities within the Toluca Valley Metropolitan Area (TVMA), and 8 municipalities within the Cuernavaca Metropolitan Area. The three metropolitan areas showed significant differences in terms of air quality perception, risk perception, attitudes, and causal attribution perception, but health-related perception did not have significant differences among the areas. The MCMA exhibited higher knowledge about air pollution, although it associated the causes with urban activities such as car usage, while the Toluca and Cuernavaca areas linked this issue to the burning of garbage, coal, wood, and agricultural activities. Although residents expressed concern about air pollution, climate change, and their effects, they do not know how to act to contribute to the solution.
